How has Westwood Executive House's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Westwood Executive House, covering report years 2019–2024. Its ENERGY STAR score went from 63 in 2019 to 94 in 2024 (+31 points); its best year on file was 2022, at 96. Site EUI moved from 36.6 kBtu/ft² (2019) to 31.3 kBtu/ft² (2024), a 14% decrease. Reported emissions went from 174 tCO₂e to 150 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 94 mean?
ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 falls in band A — high performer (85–100). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In California, 65% of scored buildings are at 75 or above.
Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Westwood Executive House's 31.3 kBtu/ft² across 79,203 sq ft works out to about 2.5 billion Btu (727 MWh-equivalent) in 2024. The disclosure also reports 282,281 kWh of electricity for the year.
